Abstract

AbstractIn recent years, biocatalysts have emerged as crucial tool in organic synthesis, particularly for the production of drug intermediates and precursors, e.g., the synthesis of hydroxamic acids. Traditionally, hydroxamic acids were synthesized using organic chemistry methods. However, with the growing emphasis on sustainable and environment‐friendly practices, the chemical industry has increasingly turned towards green synthesis approaches. The significance of hydroxamic acids in medicinal chemistry has also contributed to the changing trends. Following the approval of certain hydroxamic acids as histone deacetylase (HDAC) inhibitors for cancer treatment by the Food and Drug Administration (US‐FDA), there has been a renewed focus on their synthesis and the development of derivatives with improved properties. As an alternative route, amidases have emerged as promising biocatalysts for hydroxamic acid synthesis through their acyltransferase activity. Recent advancements in the synthesis approaches for hydroxamic acids are reviewed. The biocatalytic routes are explored, emphasizing the use of amidases and their acyltransferase activity. The scope and potential applications of this chemoenzymatic approach in synthesizing various hydroxamic acids and their derivatives are discussed. Such advancements have the potential to revolutionize the production of these important compounds, making the synthesis process more sustainable, efficient, and economically viable.
